The ACTING DEPUTY PRESIDENT ( Senator Polley ) (16:10): A letter has been received from Senator David Pocock: Pursuant to standing order 75, I propose that the following matter of public importance be submitted to the Senate for discussion: Noting the open letter to the Prime Minister from almost 2,300 health professionals raising concerns about the health impacts of the Middle Arm development, the Senate accepts the need to further scrutinise the development by way of a Senate committee inquiry. Is the proposal supported? More than the number of senators required by the standing orders having risen in their places— The ACTING DEPUTY PRESIDENT: I understand that times have been organised.
